Optimal Sensor Location based on the Observability Measures for an Anaerobic Wastewater Treatment Process

In this paper the choice of the optimal sensor location, especially of the gas product in an anaerobic wastewater treatment process is discussed. First, we have applied the observability measures theory considered in Waldraff, et al. (1998) on the distributed parameter model of an anaerobic wastewater treatment process (Schoefs, et al., 2003), which is discretized by using the orthogonal collocation method. Then a state observer has been implemented to illustrate the results. These investigations lead to recommend appropriate sensor location
